TIRE-SHOE a Specification of Letters Patent.

v Application-filed November 4, 19 18. Serial No. 260,979.

This invention relates to new and useful improvements in a tire shoe. I

The object of the invention is to provide a shoe of the characterdescribed which is designed to be placed around the inner tube of apneumatic tire opposite a blow-out, or a-weak place in the casing, so asto strengthen the casing and prevent the inner tube from being burst orblown-out.

Another object of the invention resides in the provision of a shoe ofthe character described which may be securely fastened around the innertube before it is placed in the casing, and which will be securely heldin position against slippage or displacement.

A further feature of the invention resides in the provision of aflexible detachable strip forming a part of the shoe and interposedbetween the inner tube, and the free edges of the shoe, which preventsthe tube from becoming pinched between said free edges, and includesmeans for securing said flexible detachable strip in position.

With the above and other objects in view, the invention has particularrelation to certain novel features of construction, arrangement ofparts, and use, an example of which is given in this specification, andillustrated in the accompanying drawings, wherein:

Figure 1, is a side elevation of the shoe.

Fig. 2, is a view of the inner side thereof.

Fig. 3, is a transverse sectional view of a tire casing and tube showingthe shoe within the casing, and

Fig. 4, is a plan view of a flexible material employed.

Referring now more particularly to the drawings wherein like numerals ofreference designate similar parts in each of the figures, the numeral 1,refers to a pneumatic tire casing, having the inner inflatable tube 2therein. In case a blow-out 3, occurs, in.

the casing, or it becomes otherwise weakened at any particular place,the shoe 4 is fitted around the tube which is then placed in the casingso as to bring the shoe opposite said blowout. This shoe is formed ofstrong rubberized fabric, or other strong flexible material, and itsfree edges are provided with eyelets 5, to receive the lace 6, by meansof which the free edges of the shoe are laced together around the tubefrom end to end. For the purpose of protecting the tube against comingin' contact with the lace 6, or becoming pinched between the free edgesof the shoe, I have interposed between said tube and the lace a longstrip of flexible detachable material, preferably rubberized fabric,built up of a plurality of plies as 7,

8 and 9, each ply being somewhat narrower than the preceding one, asshown in Figs. 3 and l, and the lace passes between said plies 8 and 9at a sufficient number of points to secure the strip in position, as isalso shown in Fig. 3. The tire may be then placed upon the rim andcompletely inflated. The shoe is thus held firmly in position and willnot work circumferentially around the casing and the protectingdetachable strip interposed between the inner tube and the lacing isheld securely in position. It is obvious that a shoe similar to this maybe placed over a. blowout and laced onto the casing to strengthen theweakened part. In case this is done, the flexible strip is not used.

What I claim is:

In a device of the characterdescribed, the

combination with an outer casing and an Patented Apr. 1, 1919.

inner inflatable tube, of a shoe formed of flexible material and fittedWithin the casing, and surrounding said tube, each of the free edges ofthe shoe being provided with perforations, a protecting strip formed oflayers of flexible mateiial, fitted between said inner tube and the freeedges of said shoe, each layer being narrower than the HENRY E.
